W24 Embedded Web Server

2-80 AT+i Commands Reference Manual May 31, 2008

<BODY>

Dial To:<INPUT type='text' name='ISP1' value='~ISP1~'>

</FORM>

</BODY>

</HTML>

Note that the variable name is used in the NAME field, while ~<parameter name>~ is used to

display the current value.

After activating SUBMIT, the browser issues a GET command to W24's web server that includes

the parameter's name and the new value entered in the form. The page is then served to the

browser again with the updated values.

In addition to specifying W24 configuration parameters and Parameter Tags, it is also possible to

display W24 reports and W24's MAC address. For example:

<table>

<tr>

<td width=250><b>MAC Address: ~MACA~ <b></td>

</tr>

<tr>

<td width=250><b>Bootblock Version: BBIC~RP3~</b> </td>

<td width=400><b>Firmware Version: ~RP1~</b></td>

</tr>

<tr>

<td width=250><b>Serial Number: ~RP5~ </b></td>

<td width=400><b>Hardware Version: ~RP0~</b></td>

</tr>

</table>

Security and Restrictions

The authorization to view and update W24's configuration parameters, firmware, or application

website via the web can be password-protected using the AT+iRPG parameter (Remote

Parameter Group/Password).

When the RPG parameter in a W24 device contains a value, it is considered a password that

restricts remote W24 parameter viewing/updates. By default, W24's configuration site can be

viewed (browsed), unless the Security Disable Mode (SDM) bit 3 is set, in which case the user is

authenticated by submitting the RPG value. To enable remote updates, a distant user is always

authenticated by submitting that value. The W24 configuration site includes an authentication

form that automatically pops up on the remote browser when parameter updates are attempted.

The password submitted through this form must match the actual value of W24's local RPG

parameter. Otherwise, remote value updates are rejected.
